( Live view 20x magnified focusing ) .
This is probably the most important improvement in this whole thread .

Eliminate the optical and all mirrors ( saves money , reduces weight and vastly improves focusing accuracy with no extra cost in the end product ) .

Remote IR shutter from the back of the camera ( another remote sensor on the rear of the Camera ) .

( Built in Possibility ) for live view feed to one of several large screens ( sold separately ) . I want the 4 X 6 inch live view for focusing my a-900 right now .

( 4 X 6 inch with 20x magnified focusing view added to this would complete a near perfect system . ) No more need to squint eyes and strain to see the focus then later find all are blurred on the computer monitor .

This would instantly increase the value of all a-900 cameras already out there .
